GeForce GTX Titan X vs Radeon RX 6800

Intro

Compare all that to the Radeon RX 6800, which comes with a GPU core clock speed of 1700 MHz, and 16384 MB of GDDR6 memory set to run at 2000 MHz through a 256-bit bus. It also is comprised of 3840 Stream Processors, 240 TAUs, and 96 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Radeon RX 6800 should theoretically perform much faster than the GeForce GTX Titan X in general. (explain)

Radeon RX 6800		524288 MB/sec
GeForce GTX Titan X		336000 MB/sec
	Difference: 188288 (56%)

Texel Rate

The Radeon RX 6800 is a lot (more or less 113%) more effective at texture filtering than the GeForce GTX Titan X. (explain)

Radeon RX 6800		408000 Mtexels/sec
GeForce GTX Titan X		192000 Mtexels/sec
	Difference: 216000 (113%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 6800 is a better choice, by far. (explain)

Radeon RX 6800		163200 Mpixels/sec
GeForce GTX Titan X		96000 Mpixels/sec
	Difference: 67200 (70%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
